I have a 2015 LT and there's no gauge. I was hoping to replace A Pillar with a pod pillar and placing a gauge in there. But if you really need to know, there an app for Android and like a $20 OBD 2 reader that connects via Bluetooth and you can see everything current about your car. I used the reader in my Grand Cherokee to watch the codes I was getting. Comes in handyNo temperature gauge on 2015 Trad 2015?
